T 0 all whom it may concern: I Be it known that I, IRVING E. Asnn, citizen of the United States, residing Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Heaters or Va )orizers of which I do declare the I 7 following to be a specification.

My invention relates to electric heater or vaporizer and more particularly to the type of electric heater or vaporizer which is adapted tobe interposed in a conduitfor the purpose of heating or vaporizing gas or liquid during the passage of the same through. such conduit. It has, for its object the provision of an improvedand simpli tied structure of the type of heater or vaporize-r referred to. With this and other objects in view, it consists of the structures, combinations and arrangements of parts hereinafter described and claimed.

In the drawings, Fig. l is a side elevation of a carburetor and fuel pipe line including a gasket embodying my said invention. F ig. 2, is a front elevation of a heating element forming part of my said invention. Fig. 2, is a front elevation of a similar heatingcle ment preferably positioned so that the wires run approximately at right angles to the wires in said Fig. 2. Fig. 4;, is a bot-- tomedge plan of the frame forming part of Fig. 2. Fig. 5, is aninterior or front elevation of a gasket plate adapted to contain the hereinafter described heating ele ment, or elements. Fig. 6, is a central hori zontal section through a gasket containing said heating elements. F 7, is a horizontal section of said gasket on the line L-B, of Fig. 5. Fig. 8, is a diagrammatic view of a normally open electric circuit, embodying said heating elements.

In the drawings, X is carburetor of any suitable structure from which extend fuelconducting pipe lines 1 and 2 respectively, in one of which pipelines is interposed a gasket comprising gasket plates 3 and a.

\Vithin said gasket is positioned one or more similar heating elements each comprising a plurality of turns of wire, 5, wound upon a flat frame 6 of insulating material, preferably mica, which frame is preferably notched in two opposing edges as at 6 to receive the wire at its turning points, and which frame has a central aperture formed therein corresponding approximately to the interior diameter of said pipe, said aperture being crossed by said wire. The terminals of said heating ele nient are preferably secured in any suitable manner, as by soldering, to the inner ends of binding posts 7 and S rcspectively,which extend into said gasket, but if desired the hereinafter (lescribedbars may instead be connected directly to said binding posts.

It will be observed that as thus far described, the turns of said wire are in electrical well as mechanical series. that very simple operation. But one of the dis advantages of such structure is that if one turn of the wire is broken,- the whole of the heating element is made inoperative. (hie ofithe principal features of my present ,in' vention is the transforming of said turns of wire from electric serial relationshipto each other to electric parallel relationship to each other. This I accomplish by bringing into contact with a plurality or all. of said turns near each end of said frame, electric connecting bars 9 and lO, respectively, common to said plurality of turns, whereby the several'turns of said wire are electrically cross-connected and made electrically parallel to each. other, .Said connecting bars may be loosely positioned in said gasket. but I prefer to mould them in position when moulding the gasket plate or plates in which they are adapted to lie. Said gaskct plates are of any suitable insulating material. Each of said plates has an aperture 11 formed therein corresponding approXi mately to the interior diameter of the pipe in which said gasket is interposed and has apertures 12 formed therein for the passage of rivets or bolts for securing them together.

Preferably two of said heating elements are positioned in each gasket, in which event they are preferably positioned so that the turns of the wire of one of them extend at approximatelyright angles to the turns of wire of the other. Each heating element is substantially independent of and parallel to the other. both being connected to the same said binding posts; but in their preferred position at right angles to each other they cooperate to form a checker-board screen which more finely divides'the current of gas or liquid and distributes the heat through it more effectually than if the turns of wire were all in one direction.

It is observed that both of said gasket plates may be recessed so that one heating the windingof the wire on said frame is a f element ,will lie in one plate andthe other heating element in the other plate, or so that one heating element may lie partly in one plate and partly in the other, but 1 pre fer to recess only one of the plates, as 3, and to position the heating element or ele ments therein and to make the opposing plate 4 flat.

After winding the wire of the heating ele ment upon its frame, I preferably fill the spaces between the turns of wire from the periphery of the central aperture of the frame to its outer edges, with suitable cement to prevent the collection in said spaces of moisture or particles of liquid.

In Fig. 8, is shown a diagram of a normally open electric circuit comprising any suitable source of electricity, as a battery 13, a normally open contact, as a starting switch 14, and two'of said heating elements. If desired, other translation devices (not shown) may be interposed in said circuit. Packing strips of insulating material, as 15, 16, are preferably positioned between said heating elements at the edges thereof.

In operation, when said circuit is closed,

gas or liquid fuel passing through said pipe line to the engine (not shown), is heated or vaporized so that it may be promptly exploded by an electric spark in a cold cylinder.

hat I claim is Asa new article of manufacture a heating element comprising a frame of insulating material having an aperture formed there through for the passage of fluid, of a wire wound upon said frame, some of the turns of said. wire extending across said aperture, an electric conductor extend ng across and in contact with a plurality of the turns of said wire near one end of said frame, and a second electric conductor extending across and in contact with a plurality of the turns of said wire near the opposite end of said frame.

In testimony whereof, I hereunto a'l'lix my signature, in presence of two witnesses.

IRVING E. ASKE.
